At least on google+ they didn't just remove the ability to reload. They replaced it with the ability to go back to the top of your stream without reloading everything.
Since google+ already loads new posts automatically. This has the same practical effect as before in most cases. But with the advantage of faster loading since it doesn't reload everything because it doesn't need to.
